ANNUNCIATOR-SETTING DEVICE.

Application filed July 31,

T 0 all whom it may concern Be it known that I, SALVATORE D. Rosn, acitizen of the United States, and resident of the city of fieattle,county of King, State of Washington, have invented certain new anduseful Improvements in Annunciator- Setting Devices, 01 which thefollowing is a specification.

This invention relates to improvements in 'annunciators, and moreparticularly to annunciator setting mechanism whereby the lift rods,used in the usual type of electrically operated annunciators for movingthe station designation pointers or blocks from released to setposition, may be actuated to set the released pointers.

The principal object of the present invention is to provide a device ofthe above character that may be attached, or applied. to annunciators ofthe most common types without necrossitating alteration in theirconstruction, and which by its use will save time and energy of anoperator, especially where such annunciators are used in passengerelevators.

Another object of the invention is to provide setting mechanism of theabove character that may be operated both electrically on the closing ofan electric circuit through a magnet, or may be operated manually. 5

A still further object is to provide a setting device which may be madeand installed at a relatively small expense and which will in no wayinterfere with the operation of the parts of an annunciator as theyalready exist.

In accomplishing these and other objects of the invention I haveprovided the improved details of construction, the preferred forms ofwhich are illustrated in the accompanying drawings, wherein Figure l isa partial view of an annunciator, equipped with setting mechanismembodied by the present invention.

Figure 2 is a side view of part of the annunciator mechanism.

Referring more in detail to the draw ings 1 designates the lower end ofthe housing oi an annunciator which may be of the character nowgenerally in use in passenger elevators, and which comprises a pluralityof electrically controlled blocks or pointers which are individuallymovable and when 1920. Serial No. 400,342.

moved to certain positions designate certain points of call whereattention is required.

In the present device, the indicators comprise small blocks, or plates2, which are pivotally supported byarms 3 and when in set position aredisposed above individual openings 4.- in the front of the housing 1.tach block 2 is normally held in set position by a yieldable latch, notshown, which is adapted to be magnetically moved by the closing of anelectric circuit, through a magnet (not shown), by pressing a switchbutton at some point of call or station, to release the block so that itwill fall to position in front of its respective opening 4 and can beseen by an operator. These blocks are moved back to set position afterbeing released by upward movement oi. a vertical rod 6 which is mountedslidably in the housing and has laterally extended arms 7 which willliftingly engage the different arms 3 when the rod is moved upwardly.

Applicant has learned from experience that repeated re-setting of thesignals in elevator annuneiators becomes very tiresome, especially wherethe o erator has to reach or turn in order to ave access to the settingrod. Also the operators attention is often taken from the manipulationoil? the elevator control lever by such reach ing which makes accidentsmore apt to occur.

The present invention seeks therefore to overcome these apparentdifiiculties and disadvantages by a mechanism especially adapted for usein elevator annunciators, which may be either electricall or manuallyactuated, without apparent e ort and with out detracting attention fromthe Work of operating the elevator control lever.

The present device consists of a lever 10 that is pivotally mountedintermediate its ends by a pivot bolt, screw or pin 11, upon a bracket12 which is mounted in any suitable manner upon a wall of the housing 1.The lever 10 has its inner end disposed beneath the lower end of thelift rod 6 and mounted above the lever, between this end and the pivotpin 11, is a magnet 5 having a core 15 extended downwardly andterminating at a short distance above the lever. Circuit wires 16 and 17are connected with the magnet coil through any suitable source ofelectricity, as indicated by the battery at 18, and connect with acircuit closing switch button 19 which may be mounted on the lever 20which is actuated to control movement of the elevator wherein theannunciator is used.

The wires 16 and 1? are suit-ably insulated and are attached to theouter end of the lever 1.0 and depend to an accessible position adjacentthe control lever where they may be equipped with a ball or othersuitable handle 22 which may be easily grasped.

From the ball the wires are extended to the switch button 19 that ismounted on the control lever 25 of the elevator, and which is of thecharacter that will cause a circuit to be closed through the wires whenpressed inwardly.

WVith the parts so constructed and assembled, the lever 10 may beactuated manually by a downward pull on the ball 22, or it may beactuated electrically by closing an electric circuit through the magnet5, by pressure on the switch button 19.

Either manner of actuation will. cause the bar 6 to be lifted and theblocks 2 re-set after being released.

Such mechanism will save the time and energy of an elevator operator andwill add safety to elevator operation.

It is apparent that various changes in the shape of the lever, itsmounting device, also in the method of mounting the circuit closingbutton could be made without departing; from thespirit of the invention,and I do not wish to limit the construction only to the details shown.

Having thus described my invention, what I claim as new therein anddesire to secure by Letters-Patent, is:

In an annunciator of the character de scribed, the combination with avertically shiftable signal setting rod thereof, of a lever pivotallysupported between its ends with its inner end disposed beneath said rod,an electro-magnet mounted adjacent to and cooperating with said lever,electric circuit wires for said magnet fixed to the outer end of thelever and depending therefrom, a switch connected with the lower ends ofsaid wires, whereby a circuit may be closed through the magnet to causethe lever to be magnetically lifted to actuate the signal setting rodand a handle member secured on said wires whereby said lever may bemanually operated.

Signed at Seattle, day of July 1920.
